Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to construction blocks and block structures, and particularly to construction blocks and block structures used for simple embankments, breakwaters, wave dissipation, or foot protection. Regarding block structures using blocks.

[Conventional technology and its issues] Bank protection construction is being carried out to protect sections of rivers and oceans from erosion by water currents and waves. Bank protection work is generally carried out by constructing construction blocks in front of one piece of foundation work or gauging work, and the construction blocks are used to prevent scouring by water flow and erosion by waves.

The building blocks used for this purpose are usually irregularly shaped blocks such as tetrapods. Irregularly shaped blocks are piled up in multiple layers or in random piles on top of rubble stones constructed on the floor in front of foundation work, etc., and the voids in the irregularly shaped blocks reduce the impact pressure of water currents and waves, causing damage to sections and breakwaters. etc. are protected.

However, the irregularly shaped construction blocks that have been used conventionally have the following problems.

(a) Since the irregularly shaped blocks do not have a connecting and fixing means, the blocks are not sufficiently fixed to each other when stacked. Therefore, during long-term use, individual blocks tend to move due to the impact of water currents and waves, and often collapse after construction.

(b) Because the stacking method is multi-layered or random stacking, the voids that are formed vary depending on the location and are not constant, and therefore the erosion is also not constant. Therefore, even if the stacking is orderly at the beginning of construction, erosion will occur after construction. There is a risk of it collapsing from places where it is severely affected. For this reason, the shape of the top of the block cannot be expected to be maintained, and structures cannot be built on top.

(C) It is difficult to stack irregularly shaped blocks in a stable and orderly manner due to their structure. As a result, they tend to pile up in random order, and their irregular, uneven surfaces spoil the scenery, especially in tourist areas. In addition, the area around the odd-shaped blocks after construction will attract fish and become a good fishing spot, but the unstable footing causes many accidents such as anglers falling and falling.

U Purpose of the present invention The present invention is to: ■ enable a solid structure by assembling it up and down, front and back, left and right in an orderly manner during construction, and to be able to withstand long-term use; To ensure that the water flow spaces formed between the blocks are regular and even, so that construction work can be carried out without waste, taking into full consideration the impact pressure of waves and water currents.
It is possible to prevent the resulting block structure from spoiling the landscape, and also to prevent irregular unevenness from forming on the structure so that structures can be built on top of the block structure. The aim is to provide building blocks that

[Configuration of the present invention] The configuration of the present invention taken to solve the above problems and achieve the object is as follows.

The first invention includes an upper joint body and a lower joint body, both joint bodies are connected via a support, and a fitting part is formed on an upper surface of the upper joint body and a lower surface of the lower joint body, Furthermore, both joined bodies are construction blocks each having a through hole through which a shaft can pass.

The second invention comprises an upper joint body and a lower joint body, both joint bodies are connected via a support, and a fitting part is formed on the upper surface of the upper joint body and the lower surface of the lower joint body, Furthermore, both joints have construction blocks each having a through hole through which the shaft can pass.

A mounting board having a fitting part formed on the upper surface thereof that fits with the fitting part formed on the lower joined body of the building block; and a mounting board having a fitting part formed on the lower joined body of the building block on the lower surface. a top plate on which a fitting portion is formed, the building blocks are stacked on the mounting board, and the top plate is placed on top of the top building block;
The mounting board and the top plate are a block structure connected by a connecting body passing through the construction block.

The shapes of the upper and lower joined bodies are not particularly limited, and may be, for example, prismatic or flat. The fitting part of the lower assembly is made to correspond to the fitting part of the upper assembly and the fitting part of the mounting board so that they can be fitted together, so that they do not shift from each other when stacked. Grooves that serve as water passages when the other construction blocks are joined are provided on the sides of both joined bodies, if necessary.

Further, the upper and lower joined bodies are each provided with a through hole through which the shaft can pass. Here, the concept of a through hole through which a shaft can pass includes not only cases where the axes are the same, but also cases where the axes are not the same as long as a linear connecting shaft can be penetrated through the hole.

The pillars are made of something that can withstand the load of other blocks or structures stacked on top, such as concrete filled with reinforcing bars, or concrete filled with waste tires, whose reuse has recently been researched in many ways. It is used after it has been solidified. In the latter case, the support column is covered with the tire, so it has excellent durability.

The shape of the support column may be, for example, an "I" shape, a "U" shape, or a ">" shape, in addition to the "C" shape shown in the embodiment.

Note that it is preferable that the overall shape of the building block is formed so that it can be handled as a rectangular parallelepiped because it will fit neatly when assembled vertically and horizontally.

In addition, in the case of a block structure, the building blocks are connected in the height direction, but for connection in the length and width directions, connecting tools can be fixed at appropriate locations and fixed with bolts and nuts. Doing so is optional.

The mounting board and top plate are plate-shaped with sufficient strength, and are usually made of concrete with reinforcing bars. The shapes of the fitting parts formed on the upper surface of the mounting board and the lower surface of the top plate are not particularly limited. For example, there are protrusions, protrusions, and fitting grooves. corresponds to the fitting part of the lower assembly of the construction block to be placed, such as a fitting groove. Note that it is optional to provide connection means in each of the length direction and width direction on the mounting substrate and the top plate.

[Effects of the Invention] The present invention has the above-mentioned configuration. (a) The construction blocks can be assembled in an orderly manner vertically and horizontally, without being piled up randomly during construction, making the construction solid. , can withstand many years of use. In addition, since the building block is sandwiched between the mounting board and the top plate and joined together by a connecting body, there is no possibility of collapse due to waves or the like.

(b) The building blocks can be assembled in an orderly manner three times vertically and horizontally, and the way they are stacked is consistent, so the formed water passage space is regular and even. Therefore, construction work can be carried out without waste, taking into consideration the impact pressure of waves and water currents.

Furthermore, when used as a foundation block, conventional blocks did not have a space for water to flow through, so there were problems such as the ground being scoured by the water flow and rubble etc. sliding down. However, since the construction block according to the present application has a space formed therein, water flows through the space without interfering with the water flow, and it is possible to prevent the ground from being scoured by running water.

(c) Since the top part when constructed is formed so as to be approximately horizontal due to the top plate, the constructed structure will not spoil the landscape. In addition, since irregular irregularities are not formed on the structure, it is possible to construct structures such as platforms, and even when used as a fishing spot, the footing is good and safe, and ships can be docked alongside, as well as promenades and loading docks. It can also be used as such.
